WWPack32: exe/dll compression idea

WWPack32: exe/dll compression idea

Typical Windows EXE/DLL file contains of the following parts:

DOS EXE header
Win32 Portable Executable header
Code section(s)
Data section(s)
Resources section
Import/Export Table sections
Relocation Table section

Sections making EXEs so big are Code, Data, Resources and Relocation Table...

And here the WWPack32 idea comes: if you compress the biggest sections, and add at the end of the file a small decompression routine, the file will be much smaller running exactly as the original one!

Have a look at the following:

file before compression

MZ

PE

Code

Data

Resources

I/E

Reloc

file after compression

MZ

PE

Code

Data

Resources

I/E

WWP+Reloc

The biggest sections have been squeezed thus makes compressed file much smaller :)
